Cross-diffusion effects on an exponentially stretching sheet in a doubly stratified viscous fluid

Abstract

This article analyses the influence of double stratification and cross-diffusion effects on the viscous fluid flow over a porous sheet stretching exponentially by applying the velocity slip at the boundary. The numerical solutions to the governing equations are evaluated using successive linearisation procedure and the Chebyshev collocation method. The results obtained are compared with the existing results in the literature for special cases. The influence of the pertinent parameters on the physical quantities are displayed through graphs.
